  • Flash: How to preload upcoming SWF while current one plays

    - by pthesis
    I have a Flash slideshow that plays SWFs listed in an XML file. I would like to have the upcoming SWF load while the current one displays. I've tried all sorts of combinations of LoadMovie and LoadMovieNum, including creating an empty movie clip, but there's something I'm just not getting. Right now, after making the first round through all the files, it transitions smoothly from slide to slide, but I'd like for it to preload so that it transitions without the "Loading..." screen the first time around. It can be viewed here: slideshow Where should I put the LoadMovie line to load the next file (image[p+1]), and how should it look? function loadXML(loaded) { if (loaded) { xmlNode = this.firstChild; image = []; description = []; total = xmlNode.childNodes.length; for (i=0; i<total; i++) { image[i] = xmlNode.childNodes[i].childNodes[0].firstChild.nodeValue; description[i] = xmlNode.childNodes[i].childNodes[1].firstChild.nodeValue; } firstImage(); } else { content = "file not loaded!"; } } xmlData = new XML(); xmlData.ignoreWhite = true; xmlData.onLoad = loadXML; xmlData.load("xmlfile.xml"); ///////////////////////////////////// back_btn.onRelease = function () { backImage(); }; next_btn.onRelease = function () { nextImage(); }; p = 0; function nextImage() { if (p<(total-1)) { p++; trace(this); _root.mc_loadfile.loadMovie (image[p]); _root.movie_name.text = image[p]; next_btn._visible = true; back_btn._visible = true; if (getBytesLoaded() == getBytesTotal()) slideshow(); } else if (p == (total-1)) { p = 0; firstImage(); } } function backImage() { clearInterval(myInterval); if (p>0) { --p; _root.mc_loadfile.loadMovie (image[p]); _root.movie_name.text = image[p]; next_btn._visible = true; if (p != 0) { back_btn._visible = true; } else { back_btn._visible = false; } slideshow(); } } I'd appreciate any help.

  • Redirecting one file to another using dub2 and strtok

    - by Sergiy Zakharov
    OK, here goes. I have to write a program, in which I need to use strtok and dup2 to redirect one file to another, but I need to also have the user to actually put the command cat < file1 file2, but not from the shell, but instead by using my program. That's why I need strtok. And the reason my program doesn't work is probably because of that, because I don't really understand how strtok works. I found a similar program on the internet, but they just take the ls command and redirect it to the file. That's it. My program is much more complicated. I mean, it would've been easier just to say in shell cat < file1 file2, but for some reason they want us to do it this way. So, anyways, here is what I have so far (here I just combined what I have found on the internet with what I already had from before. We had to do something similar but then the user would just go ls or ls -l. Very simple stuff. This is much harder, for me, at least.) #include <fcntl.h> #include <unistd.h> #include <stdio.h> #include <errno.h> #include <sys/wait.h> #include <string.h> int main() { pid_t pid; char line[256]; char *args[129]; int i; int fd; int status; char *temp; while (1) { printf(">"); if (fgets(line, 256, stdin) == 0) { exit(0); } else { pid = fork(); if (pid == 0) { i = 0; temp = strtok("<",line); while (temp != NULL) { args[i++] = temp; temp = strtok(">",line); args[i] = '\0'; } fd = open("hello", O_RDONLY); dup2(fd, STDIN_FILENO); fd = open("world", O_WRONLY|O_CREAT|O_TRUNC, S_IRWXU); dup2(fd, STDOUT_FILENO ); close(fd); execvp(args[0], args); } else { close(fd); wait(&status); } } } } Any help would be greatly appreciated.

  • Fill 4 input with one textarea

    - by Patrice Poliquin
    I have a question for the community. My problem is that I have 4 input files with a maxlength of 60 caracters for a total of 240 caracters. Because the "backend" of the customer's system, it need to be 4 differents inputs max to be inserted and they say it is not user-friendly to fill 4 fields. My solution I want to make a textarea and when you fill it, il complete the 4 fields. [input text #1] max60 [input text #2] max60 [input text #3] max60 [input text #4] max60 [textarea max 240] What I am trying to do is to make by javascript/jQuery to fill up the four field while typing in. At the moment, here is my code. $(document).ready(function() { // My text area $("#inf_notes").bind('keydown', function () { var maxLength = 240; if ($(this).val().length <= 60) { // The first 60 caracters $('#inf_notes_1').val($(this).val()); } if ($(this).val().length > 60 && $(this).val().length <= 120) { // If more then 60, fill the second field $('#inf_notes_2').val($(this).val()); } // If 121 - 180 ... // If 181 - 240 ... if($(this).val().length == 240) { $(this).val($(this).val().substring(0, maxLength)); $('.alert_textarea').show(); // Simple alert else { $('.alert_textarea').hide(); } }); }); It actually works for the first one, but I would like to have some feedbacks to help me complete the script to fill the 3 nexts. Any guess to complete it? -- EDIT #1 I found a way that could maybe work! When the first input is completly filled, it will jump to the next field with a .focus() $(".inf_notes").bind('keydown', function () { var notes1 = $('#inf_notes_1').val(); var notes2 = $('#inf_notes_2').val(); var notes3 = $('#inf_notes_3').val(); if (notes1.length == 60) { $('#inf_notes_2').focus(); } if (notes2.length == 60) { $('#inf_notes_3').focus(); } if (notes3.length == 60) { $('#inf_notes_4').focus(); } });

  • Post and get at the same time in php

    - by user225269
    Do you have any suggestions with my problem. I need to use get and post at the same time. Get because I need to output what the user has typed. And post because I need to access the mysql database in relation to that input. It looks something like this: <form name="x" method="get" action="x.php"> <input name="year" type="text"> <select name="general" id="general"> <font size="3"> <option value="YEAR">Year</option> </form> This will output the contents of mysql depending on what the user will check: <form name="y" method="post" action"y.php"> <input name="fname" type="checkbox"> </form> And the form action of those two combined will look something like this: <?php if($_POST['general'] == 'YEAR'){ ?> <?php echo $_GET["year"]; ?> <?php $result2 = mysql_query("SELECT * FROM student WHERE student.YEAR='$syear'"); ?> <table border='1'> <tr> <?php if ( $ShowLastName ) { ?><th>LASTNAME</th><?php } ?> <?php if ( $ShowFirstName ) { ?><th>FIRSTNAME</th><?php } ?> </tr> <?php while ( $row = mysql_fetch_array($result2) ) { if (!$result2) { } ?> <tr> <td><?php echo $row['IDNO']?> </td> <td><?php echo $row['YEAR'] ?> </td> <?php if ( $ShowLastName ) { echo('<td>'.$row['LASTNAME'].'</td>'); } ?></td> <?php if ( $ShowFirstName ) { echo('<td>'.$row['FIRSTNAME'].'</td>'); } ?> I really get lots of undefined errors when I do this. What can you recommend that I should do in order to get the value inputted by the user together with the mysql data.

  • [Delphi] open text files in one application

    - by Remus Rigo
    hi all I want to write an text editor and to assign the txt files to it. My problem is that I want to have only one instance running and when a new file is opened to send the filename to the first app that is already running... (I want to do this using mutex). Here is a small test DPR looks like this uses Windows, Messages, SysUtils, Forms, wndMain in 'wndMain.pas' {frmMain}; {$R *.res} var PrevWindow : HWND; S : string; CData : TCopyDataStruct; begin PrevWindow := 0; if OpenMutex(MUTEX_ALL_ACCESS, False, 'MyMutex') <> 0 then begin repeat PrevWindow:=FindWindow('TfrmMain', nil); until PrevWindow<>Application.Handle; if IsWindow(PrevWindow) then begin SendMessage(PrevWindow, WM_SYSCOMMAND, SC_RESTORE, 0); BringWindowToTop(PrevWindow); SetForegroundWindow(PrevWindow); if FileExists(ParamStr(1)) then begin S:=ParamStr(1); CData.dwData:=0; CData.lpData:=PChar(S); CData.cbData:=1+Length(S); SendMessage(PrevWindow, WM_COPYDATA, 0, DWORD(@CData) ); end; end; end else CreateMutex(nil, False, 'MyMutex'); Application.Initialize; Application.CreateForm(TfrmMain, frmMain); Application.Run; end. PAS: type TfrmMain = class(TForm) memo: TMemo; private procedure WMCopyData ( var msg : TWMCopyData ) ; message WM_COPYDATA; public procedure OpenFile(f : String); end; var frmMain: TfrmMain; implementation {$R *.dfm} procedure TfrmMain.WMCopyData ( var msg : TWMCopyData ) ; var f : String; begin f:=PChar(msg.CopyDataStruct.lpData); //ShowMessage(f); OpenFile(f); end; procedure TfrmMain.OpenFile(f : String); begin memo.Clear; memo.Lines.LoadFromFile(f); Caption:=f; end; this code should be ok, but if i want to open a text file (from the second app), the first app receives a message like this: thanks

  • UpdatePanel, JavaScript postback and changing querystring at same time in SharePoint Search Page

    - by Lee Dale
    Hi Guys, Been tearing my hear out with this one. Let me see if I can explain: I have a SharePoint results page on which I have a Search Results Core WebPart. Now I want to change the parameter in the querystring when I postback the page so that the WebPart returns different results for each parameter e.g. the querystring will be interactivemap.aspx?k=Country:Romania this will filter the results for Romania. First issue is I want to do this with javascript so I call: document.getElementById('aspnetForm').action = "interactivemap.aspx?k=Country:" + country; Nothing special here but the reason I need to call from Javascript is there is also a flash applet on this page from which the Javascript calls originate. When the javascript calls are made the page needs to PostBack but not reload the flash applet. I turned to ASP.Net AJAX for this so I wrapped the search results webpart in an update panel. Now if I use a button within the UpdatePanel to postback the UpdatePanel behaves as expected and does a partial render of the search results webpart not reloading the flash applet. Problem comes because I need postback the page from javscript. I called __doPostBack() as I have used this successully in the past. It works on it's own but fails when I first call the above Javascript before the __doPostBack() (I also tried calling click() on a hidden button) the code for the page is at the bottom. I think the problem comes with the scriptmanager not allowing a partial render when the form post action has changed. My questions are. A) Is there some other way to change the search results webpart parameter without using the querystring. or B) Is there a way around changing the querystring when doing an AJAX postback and getting a partial render. <asp:Content ContentPlaceHolderID="PlaceHolderFullContent" runat="server"> function update(country) { //__doPostBack('ContentUpdatePanel', ''); //document.getElementById('aspnetForm').action = "interactivemap.aspx?k=ArticleCountry:" + country; document.getElementById('ctl00_PlaceHolderFullContent_UpdateButton').click(); } Romania <div class="firstDataTitle"> <div class="datatabletitleOuterWrapper"> <div class="datatabletitle"> <span>Content</span></div> </div> <div class="datatableWrapper"> <div class="dataHolderWrapper"> <div class="datatable"> <div> <div class="searchMain"> <div class="searchZoneMain"> <asp:UpdatePanel runat="server" id="ContentUpdatePanel" UpdateMode="Conditional"> <ContentTemplate> <WebPartPages:webpartzone runat="server" AllowPersonalization="false" title="<%$Resources:sps,LayoutPageZone_BottomZone%>" id="BottomZone" orientation="Vertical" QuickAdd-GroupNames="Search" QuickAdd-ShowListsAndLibraries="false"><ZoneTemplate></ZoneTemplate></WebPartPages:webpartzone> <asp:Button id="UpdateButton" name="UpdateButton" runat="server" Text="Update"/> </ContentTemplate> </asp:UpdatePanel> </div> </div> </div> </div> </div> </div>

  • Regular expression to remove one parameter from query string

    - by Kip
    I'm looking for a regular expression to remove a single parameter from a query string, and I want to do it in a single regular expression if possible. Say I want to remove the foo parameter. Right now I use this: /&?foo\=[^&]+/ That works as long as foo is not the first parameter in the query string. If it is, then my new query string starts with an ampersand. (For example, "foo=123&bar=456" gives a result of "&bar=456".) Right now, I'm just checking after the regex if the query string starts with ampersand, and chopping it off if it does. Example edge cases: Input | Output -------------------------+----------------- foo=123 | (empty string) foo=123&bar=456 | bar=456 bar=456&foo=123 | bar=456 abc=789&foo=123&bar=456 | abc=789&bar=456 Edit OK as pointed out in comments there are there are way more edge cases than I originally considered. I got the following regex to work with all of them: /&foo(\=[^&]*)?(?=&|$)|^foo(\=[^&]*)?(&|$)/ This is modified from Mark Byers's answer, which is why I'm accepting that one, but Roger Pate's input helped a lot too. Here is the full suite of test cases I'm using, and a Perl script which tests them. Input | Output -------------------------+------------------- foo | foo&bar=456 | bar=456 bar=456&foo | bar=456 abc=789&foo&bar=456 | abc=789&bar=456 foo= | foo=&bar=456 | bar=456 bar=456&foo= | bar=456 abc=789&foo=&bar=456 | abc=789&bar=456 foo=123 | foo=123&bar=456 | bar=456 bar=456&foo=123 | bar=456 abc=789&foo=123&bar=456 | abc=789&bar=456 xfoo | xfoo xfoo&bar=456 | xfoo&bar=456 bar=456&xfoo | bar=456&xfoo abc=789&xfoo&bar=456 | abc=789&xfoo&bar=456 xfoo= | xfoo= xfoo=&bar=456 | xfoo=&bar=456 bar=456&xfoo= | bar=456&xfoo= abc=789&xfoo=&bar=456 | abc=789&xfoo=&bar=456 xfoo=123 | xfoo=123 xfoo=123&bar=456 | xfoo=123&bar=456 bar=456&xfoo=123 | bar=456&xfoo=123 abc=789&xfoo=123&bar=456 | abc=789&xfoo=123&bar=456 foox | foox foox&bar=456 | foox&bar=456 bar=456&foox | bar=456&foox abc=789&foox&bar=456 | abc=789&foox&bar=456 foox= | foox= foox=&bar=456 | foox=&bar=456 bar=456&foox= | bar=456&foox= abc=789&foox=&bar=456 | abc=789&foox=&bar=456 foox=123 | foox=123 foox=123&bar=456 | foox=123&bar=456 bar=456&foox=123 | bar=456&foox=123 abc=789&foox=123&bar=456 | abc=789&foox=123&bar=456 Test script (Perl) @in = ('foo' , 'foo&bar=456' , 'bar=456&foo' , 'abc=789&foo&bar=456' ,'foo=' , 'foo=&bar=456' , 'bar=456&foo=' , 'abc=789&foo=&bar=456' ,'foo=123' , 'foo=123&bar=456' , 'bar=456&foo=123' , 'abc=789&foo=123&bar=456' ,'xfoo' , 'xfoo&bar=456' , 'bar=456&xfoo' , 'abc=789&xfoo&bar=456' ,'xfoo=' , 'xfoo=&bar=456' , 'bar=456&xfoo=' , 'abc=789&xfoo=&bar=456' ,'xfoo=123', 'xfoo=123&bar=456', 'bar=456&xfoo=123', 'abc=789&xfoo=123&bar=456' ,'foox' , 'foox&bar=456' , 'bar=456&foox' , 'abc=789&foox&bar=456' ,'foox=' , 'foox=&bar=456' , 'bar=456&foox=' , 'abc=789&foox=&bar=456' ,'foox=123', 'foox=123&bar=456', 'bar=456&foox=123', 'abc=789&foox=123&bar=456' ); @exp = ('' , 'bar=456' , 'bar=456' , 'abc=789&bar=456' ,'' , 'bar=456' , 'bar=456' , 'abc=789&bar=456' ,'' , 'bar=456' , 'bar=456' , 'abc=789&bar=456' ,'xfoo' , 'xfoo&bar=456' , 'bar=456&xfoo' , 'abc=789&xfoo&bar=456' ,'xfoo=' , 'xfoo=&bar=456' , 'bar=456&xfoo=' , 'abc=789&xfoo=&bar=456' ,'xfoo=123', 'xfoo=123&bar=456', 'bar=456&xfoo=123', 'abc=789&xfoo=123&bar=456' ,'foox' , 'foox&bar=456' , 'bar=456&foox' , 'abc=789&foox&bar=456' ,'foox=' , 'foox=&bar=456' , 'bar=456&foox=' , 'abc=789&foox=&bar=456' ,'foox=123', 'foox=123&bar=456', 'bar=456&foox=123', 'abc=789&foox=123&bar=456' ); print "Succ | Input | Output | Expected \n"; print "-----+--------------------------+--------------------------+-------------------------\n"; for($i=0; $i <= $#in; $i++) { $out = $in[$i]; $out =~ s/_PUT_REGEX_HERE_//; $succ = ($out eq $exp[$i] ?

  • C++ custom exceptions: run time performance and passing exceptions from C++ to C

    - by skyeagle
    I am writing a custom C++ exception class (so I can pass exceptions occuring in C++ to another language via a C API). My initial plan of attack was to proceed as follows: //C++ myClass { public: myClass(); ~myClass(); void foo() // throws myException int foo(const int i, const bool b) // throws myException } * myClassPtr; // C API #ifdef __cplusplus extern "C" { #endif myClassPtr MyClass_New(); void MyClass_Destroy(myClassPtr p); void MyClass_Foo(myClassPtr p); int MyClass_FooBar(myClassPtr p, int i, bool b); #ifdef __cplusplus }; #endif I need a way to be able to pass exceptions thrown in the C++ code to the C side. The information I want to pass to the C side is the following: (a). What (b). Where (c). Simple Stack Trace (just the sequence of error messages in order they occured, no debugging info etc) I want to modify my C API, so that the API functions take a pointer to a struct ExceptionInfo, which will contain any exception info (if an exception occured) before consuming the results of the invocation. This raises two questions: Question 1 1. Implementation of each of the C++ methods exposed in the C API needs to be enclosed in a try/catch statement. The performance implications for this seem quite serious (according to this article): "It is a mistake (with high runtime cost) to use C++ exception handling for events that occur frequently, or for events that are handled near the point of detection." At the same time, I remember reading somewhere in my C++ days, that all though exception handling is expensive, it only becmes expensive when an exception actually occurs. So, which is correct?. what to do?. Is there an alternative way that I can trap errors safely and pass the resulting error info to the C API?. Or is this a minor consideration (the article after all, is quite old, and hardware have improved a bit since then). Question 2 I wuld like to modify the exception class given in that article, so that it contains a simple stack trace, and I need some help doing that. Again, in order to make the exception class 'lightweight', I think its a good idea not to include any STL classes, like string or vector (good idea/bad idea?). Which potentially leaves me with a fixed length C string (char*) which will be stack allocated. So I can maybe just keep appending messages (delimted by a unique separator [up to maximum length of buffer])... Its been a while since I did any serious C++ coding, and I will be grateful for the help. BTW, this is what I have come up with so far (I am intentionally, not deriving from std::exception because of the performance reasons mentioned in the article, and I am instead, throwing an integral exception (based on an exception enumeration): class fast_exception { public: fast_exception(int what, char const* file=0, int line=0) : what_(what), line_(line), file_(file) {/*empty*/} int what() const { return what_; } int line() const { return line_; } char const* file() const { return file_; } private: int what_; int line_; char const[MAX_BUFFER_SIZE] file_; }

  • When Logged out, one blog shows - logged in, all blogs show

    - by dgPehrson
    I've coded this Wordpress site but I'm finding difficulties with the blog area. Only one blog shows in the blog section but with I am logged in as an admin, I can see all the blogs on the page. I need it to show for everyone, whether they are logged in as a user or just a visitor to the website. I have attempted to see if it was a wordpress issue by checking the 'Settings Reading' settings and they are set just fine, showing to be 10 posts per page.. It could be something wrong with the loop. I have the blog pulling from the index.php. http://www.ilovepennycakes.com/category/blog/ Here is the direct link to the blog not showing in the feed. http://www.ilovepennycakes.com/thanksgiving-thoughts/ The code is as follows: <?php get_header(); ?> <!-- Article Loop --> <article> <?php if ( have_posts() ) : ?> <?php while ( have_posts() ) : the_post(); ?> <div class="news-top"></div> <div class="news"> <div id="post-<?php the_ID(); ?>" <?php post_class(); ?>> <div class="post-header"> <h1 class="meander"><a href="<?php the_permalink(); ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h1> <p class="likes m500"><?php comments_popup_link( '0', '1', '%' ); ?></p> <div class="clear"></div> </div><!--end post header--> <!--div class="entry clear"--> <div class="blog-content m500"> <?php if ( function_exists( 'add_theme_support' ) ) the_post_thumbnail(); ?> <?php the_content(); ?> <?php wp_link_pages(); ?> </div> <!--/div--><!--end entry--> <p class="date M500">Posted <?php the_time( 'j M Y' ); ?></p> <p class="M500"><?php edit_post_link( __( 'Edit', 'pennycakes' ), '<span>', '</span>' ); ?></p> <!--end post footer--> </div><!--end post--> </div> <div class="news-bottom"></div> <?php endwhile; /* rewind or continue if all posts have been fetched */ ?> </div><!--end navigation--> <div class="navigation index"> <div class="alignleft"><?php next_posts_link( 'Older Entries' ); ?></div> <div class="alignright"><?php previous_posts_link( 'Newer Entries' ); ?></div> <?php else : ?> <?php endif; ?> </article> <!-- //Article Loop --> Any help will be appreciated.

  • nhibernate configure and buildsessionfactory time

    - by davidsleeps
    Hi, I'm using Nhibernate as the OR/M tool for an asp.net application and the startup performance is really frustrating. Part of the problem is definitely me in my lack of understanding but I've tried a fair bit (understanding is definitely improving) and am still getting nowhere. Currently ANTS profiler has that the Configure() takes 13-18 seconds and the BuildSessionFActory() as taking about 5 seconds. From what i've read, these times might actually be pretty good, but they were generally talking about hundreds upon hundreds of mapped entities...this project only has 10. I've combined all the mapping files into a single hbm mapping file and this did improve things but only down to the times mentioned above... I guess, are there any "Traps for young players" that are regularly missed...obvious "I did this/have you enabled that/exclude file x/mark file y as z" etc... I'll try the serialize the configuration thing to avoid the Configure() stage, but I feel that part shouldn't be that long for that amount of entities and so would essentially be hiding a current problem... I will post source code or configuration if necessary, but I'm not sure what to put in really... thanks heaps! edit (more info) I'll also add that once this is completed, each page is extremely quick... configuration code- hibernate.cfg.xml <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" /> </configSections> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property> <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property> <property name="connection.connection_string_name">MyAppDEV</property> <property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider, NHibernate.Caches.SysCache</property> <property name="cache.use_second_level_cache">true</property> <property name="show_sql">false</property> <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property> <property name="current_session_context_class">managed_web</property> <mapping assembly="MyApp.Domain"/> </session-factory> </hibernate-configuration> </configuration> My SessionManager class which is bound and unbound in a HttpModule for each request Imports NHibernate Imports NHibernate.Cfg Public Class SessionManager Private ReadOnly _sessionFactory As ISessionFactory Public Shared ReadOnly Property SessionFactory() As ISessionFactory Get Return Instance._sessionFactory End Get End Property Private Function GetSessionFactory() As ISessionFactory Return _sessionFactory End Function Public Shared ReadOnly Property Instance() As SessionManager Get Return NestedSessionManager.theSessionManager End Get End Property Public Shared Function OpenSession() As ISession Return Instance.GetSessionFactory().OpenSession() End Function Public Shared ReadOnly Property CurrentSession() As ISession Get Return Instance.GetSessionFactory().GetCurrentSession() End Get End Property Private Sub New() Dim configuration As Configuration = New Configuration().Configure() _sessionFactory = configuration.BuildSessionFactory() End Sub Private Class NestedSessionManager Friend Shared ReadOnly theSessionManager As New SessionManager() End Class End Class edit 2 (log4net results) will post bits that have a portion of time between them and will cut out the rest... 2010-03-30 23:29:40,898 [4] INFO NHibernate.Cfg.Environment [(null)] - Using reflection optimizer 2010-03-30 23:29:42,481 [4] DEBUG NHibernate.Cfg.Configuration [(null)] - dialect=NHibernate.Dialect.MsSql2005Dialect ... 2010-03-30 23:29:42,501 [4] INFO NHibernate.Cfg.Configuration [(null)] - Mapping resource: MyApp.Domain.Mappings.hbm.xml 2010-03-30 23:29:43,342 [4] INFO NHibernate.Dialect.Dialect [(null)] - Using dialect: NHibernate.Dialect.MsSql2005Dialect 2010-03-30 23:29:50,462 [4] INFO NHibernate.Cfg.XmlHbmBinding.Binder [(null)] - Mapping class: ... 2010-03-30 23:29:51,353 [4] DEBUG NHibernate.Connection.DriverConnectionProvider [(null)] - Obtaining IDbConnection from Driver 2010-03-30 23:29:53,136 [4] DEBUG NHibernate.Connection.ConnectionProvider [(null)] - Closing connection

  • Foreign Key constraint violation when persisting a many-to-one class

    - by tieTYT
    I'm getting an error when trying to persist a many to one entity: Internal Exception: org.postgresql.util.PSQLException: ERROR: insert or update on table "concept" violates foreign key constraint "concept_concept_class_fk" Detail: Key (concept_class_id)=(Concept) is not present in table "concept_class". Error Code: 0 Call: INSERT INTO concept (concept_key, description, label, code, concept_class_id) VALUES (?, ?, ?, ?, ?) bind = [27, description_1, label_1, code_1, Concept] Query: InsertObjectQuery(com.mirth.results.entities.Concept[conceptKey=27]) at com.sun.ejb.containers.BaseContainer.checkExceptionClientTx(BaseContainer.java:3728) at com.sun.ejb.containers.BaseContainer.postInvokeTx(BaseContainer.java:3576) at com.sun.ejb.containers.BaseContainer.postInvoke(BaseContainer.java:1354) ... 101 more Here is the method that tries to persist it. I've put a comment where the line is: @Override public void loadConcept(String metaDataFilePath, String dataFilePath) throws Exception { try { ConceptClassMetaData conceptClassMetaData = (ConceptClassMetaData) ModelSerializer.getInstance().fromXML(FileUtils.readFileToString(new File(metaDataFilePath), "UTF8")); em.executeNativeQuery(conceptClassMetaData.getCreateStatement()); ConceptClassRow conceptClassRow = conceptClassMetaData.getConceptClassRow(); ConceptClass conceptClass = em.findByPrimaryKey(ConceptClass.class, conceptClassRow.getId()); if (conceptClass == null) { conceptClass = new ConceptClass(conceptClassRow.getId()); } conceptClass.setLabel(conceptClassRow.getLabel()); conceptClass.setOid(conceptClassRow.getOid()); conceptClass.setDescription(conceptClassRow.getDescription()); conceptClass = em.merge(conceptClass); DataParser dataParser = new DataParser(conceptClassMetaData, dataFilePath); for (ConceptModel conceptModel : dataParser.getConceptRows()) { ConceptFilter<Concept> filter = new ConceptFilter<Concept>(Concept.class); filter.setCode(conceptModel.getCode()); filter.setConceptClass(conceptClass.getLabel()); List<Concept> concepts = em.findAllByFilter(filter); Concept concept = new Concept(); if (concepts != null && !concepts.isEmpty()) { concept = concepts.get(0); } concept.setCode(conceptModel.getCode()); concept.setDescription(conceptModel.getDescription()); concept.setLabel(conceptModel.getLabel()); concept.setConceptClass(conceptClass); concept = em.merge(concept); //THIS LINE CAUSES THE ERROR! } } catch (Exception e) { e.printStackTrace(); throw e; } } ...

And also, what's important is the sql that's being generated: INSERT INTO concept_class (id, oid, description, label) VALUES (?, ?, ?, ?) bind = [LOINC_TEST, 2.16.212.31.231.54, This is a meta data file for LOINC_TEST, loinc_test] INSERT INTO concept (concept_key, description, label, code, concept_class_id) VALUES (?, ?, ?, ?, ?) bind = [27, description_1, label_1, code_1, Concept] The reason this is failing is obvious: It's inserting the word Concept for the concept_class_id. It should be inserting the word LOINC_TEST. I can't figure out why it's using this word. I've used the debugger to look at the Concept and the ConceptClass instance and neither of them contain this word. I'm using eclipselink. Does anyone know why this is happening?

  • Why does BeginReceiveFrom never time out?

    - by James Hugard
    I am writing an asynchronous Ping using Raw Sockets in F#, to enable parallel requests using as few threads as possible ("System.Net.NetworkInformation.Ping" appears to use one thread per request, but have not tested this... also am interested in using F# async workflows). The synchronous version below correctly times out when the target host does not exist/respond, but the asynchronous version hangs. Both work when the host does respond... Any ideas? (note: the process must run as Admin for this code to work) This throws a timeout: let result = Ping.Ping ( IPAddress.Parse( "192.168.33.22" ), 1000 ) However, this hangs: let result = Ping.PingAsync ( IPAddress.Parse( "192.168.33.22" ), 1000 ) |> Async.RunSynchronously Here's the code... module Ping open System open System.Net open System.Net.Sockets open System.Threading //---- ICMP Packet Classes type IcmpMessage (t : byte) = let mutable m_type = t let mutable m_code = 0uy let mutable m_checksum = 0us member this.Type with get() = m_type member this.Code with get() = m_code member this.Checksum = m_checksum abstract Bytes : byte array default this.Bytes with get() = [| m_type m_code byte(m_checksum) byte(m_checksum >>> 8) |] member this.GetChecksum() = let mutable sum = 0ul let bytes = this.Bytes let mutable i = 0 // Sum up uint16s while i < bytes.Length - 1 do sum <- sum + uint32(BitConverter.ToUInt16( bytes, i )) i <- i + 2 // Add in last byte, if an odd size buffer if i <> bytes.Length then sum <- sum + uint32(bytes.[i]) // Shuffle the bits sum <- (sum >>> 16) + (sum &&& 0xFFFFul) sum <- sum + (sum >>> 16) sum <- ~~~sum uint16(sum) member this.UpdateChecksum() = m_checksum <- this.GetChecksum() type InformationMessage (t : byte) = inherit IcmpMessage(t) let mutable m_identifier = 0us let mutable m_sequenceNumber = 0us member this.Identifier = m_identifier member this.SequenceNumber = m_sequenceNumber override this.Bytes with get() = Array.append (base.Bytes) [| byte(m_identifier) byte(m_identifier >>> 8) byte(m_sequenceNumber) byte(m_sequenceNumber >>> 8) |] type EchoMessage() = inherit InformationMessage( 8uy ) let mutable m_data = Array.create 32 32uy do base.UpdateChecksum() member this.Data with get() = m_data and set(d) = m_data <- d this.UpdateChecksum() override this.Bytes with get() = Array.append (base.Bytes) (this.Data) //---- Synchronous Ping let Ping (host : IPAddress, timeout : int ) = let mutable ep = new IPEndPoint( host, 0 ) let socket = new Socket( AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.Icmp ) socket.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.SendTimeout, timeout ) socket.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, timeout ) let packet = EchoMessage() let mutable buffer = packet.Bytes try if socket.SendTo( buffer, ep ) <= 0 then raise (SocketException()) buffer <- Array.create (buffer.Length + 20) 0uy let mutable epr = ep :> EndPoint if socket.ReceiveFrom( buffer, &epr ) <= 0 then raise (SocketException()) finally socket.Close() buffer //---- Entensions to the F# Async class to allow up to 5 paramters (not just 3) type Async with static member FromBeginEnd(arg1,arg2,arg3,arg4,beginAction,endAction,?cancelAction): Async<'T> = Async.FromBeginEnd((fun (iar,state) -> beginAction(arg1,arg2,arg3,arg4,iar,state)), endAction, ?cancelAction=cancelAction) static member FromBeginEnd(arg1,arg2,arg3,arg4,arg5,beginAction,endAction,?cancelAction): Async<'T> = Async.FromBeginEnd((fun (iar,state) -> beginAction(arg1,arg2,arg3,arg4,arg5,iar,state)), endAction, ?cancelAction=cancelAction) //---- Extensions to the Socket class to provide async SendTo and ReceiveFrom type System.Net.Sockets.Socket with member this.AsyncSendTo( buffer, offset, size, socketFlags, remoteEP ) = Async.FromBeginEnd( buffer, offset, size, socketFlags, remoteEP, this.BeginSendTo, this.EndSendTo ) member this.AsyncReceiveFrom( buffer, offset, size, socketFlags, remoteEP ) = Async.FromBeginEnd( buffer, offset, size, socketFlags, remoteEP, this.BeginReceiveFrom, (fun asyncResult -> this.EndReceiveFrom(asyncResult, remoteEP) ) ) //---- Asynchronous Ping let PingAsync (host : IPAddress, timeout : int ) = async { let ep = IPEndPoint( host, 0 ) use socket = new Socket( AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.Icmp ) socket.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.SendTimeout, timeout ) socket.SetSocketOption( SocketOptionLevel.Socket, SocketOptionName.ReceiveTimeout, timeout ) let packet = EchoMessage() let outbuffer = packet.Bytes try let! result = socket.AsyncSendTo( outbuffer, 0, outbuffer.Length, SocketFlags.None, ep ) if result <= 0 then raise (SocketException()) let epr = ref (ep :> EndPoint) let inbuffer = Array.create (outbuffer.Length + 256) 0uy let! result = socket.AsyncReceiveFrom( inbuffer, 0, inbuffer.Length, SocketFlags.None, epr ) if result <= 0 then raise (SocketException()) return inbuffer finally socket.Close() }

    - by kurt_jackson19
    I need to display a real time data from MS SQL 2005. I saw some blogs that recommend Ajax to solve my problem. Basically, right now I have my default.aspx page only just for a workaround I could able to display the data from my DB. But once I add data manually to my DB there's no updating made. Any suggestions guys to fix this problem? I need to update datagridview with out refreshing the page. Here's my code on Default.aspx.cs using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { FillDataGridView(); } protected void up1_Load(object sender, EventArgs e) { FillDataGridView(); } protected void FillDataGridView() { DataSet objDs = new DataSet(); SqlConnection myConnection = new SqlConnection (ConfigurationManager.ConnectionStrings["MainConnStr"].ConnectionString); SqlDataAdapter myCommand; string select = "SELECT * FROM Categories"; myCommand = new SqlDataAdapter(select, myConnection); myCommand.SelectCommand.CommandType = CommandType.Text; myConnection.Open(); myCommand.Fill(objDs); GridView1.DataSource = objDs; GridView1.DataBind(); } } Code on my Default.aspx <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Ajax Sample</title> </head> <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true"> <Scripts> <asp:ScriptReference Path="JScript.js" /> </Scripts> </asp:ScriptManager> <asp:UpdatePanel ID="UpdatePanel1" runat="server" OnLoad="up1_Load"> <ContentTemplate> <asp:GridView ID="GridView1" runat="server" Height="136px" Width="325px"/> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="GridView1" /> </Triggers> </asp:UpdatePanel> </form> </body> </html> My problem now is how to call or use the ajax.js and how to write a code to call the FillDataGridView() in my Default.aspx.cs page.

  • Select number of rows for each group where two column values makes one group

    - by Fábio Antunes
    I have a two select statements joined by UNION ALL. In the first statement a where clause gathers only rows that have been shown previously to the user. The second statement gathers all rows that haven't been shown to the user, therefore I end up with the viewed results first and non-viewed results after. Of course this could simply be achieved with the same select statement using a simple ORDER BY, however the reason for two separate selects is simple after you realize what I hope to accomplish. Consider the following structure and data. +----+------+-----+--------+------+ | id | from | to | viewed | data | +----+------+-----+--------+------+ | 1 | 1 | 10 | true | .... | | 2 | 10 | 1 | true | .... | | 3 | 1 | 10 | true | .... | | 4 | 6 | 8 | true | .... | | 5 | 1 | 10 | true | .... | | 6 | 10 | 1 | true | .... | | 7 | 8 | 6 | true | .... | | 8 | 10 | 1 | true | .... | | 9 | 6 | 8 | true | .... | | 10 | 2 | 3 | true | .... | | 11 | 1 | 10 | true | .... | | 12 | 8 | 6 | true | .... | | 13 | 10 | 1 | false | .... | | 14 | 1 | 10 | false | .... | | 15 | 6 | 8 | false | .... | | 16 | 10 | 1 | false | .... | | 17 | 8 | 6 | false | .... | | 18 | 3 | 2 | false | .... | +----+------+-----+--------+------+ Basically I wish all non viewed rows to be selected by the statement, that is accomplished by checking weather the viewed column is true or false, pretty simple and straightforward, nothing to worry here. However when it comes to the rows already viewed, meaning the column viewed is TRUE, for those records I only want 3 rows to be returned for each group. The appropriate result in this instance should be the 3 most recent rows of each group. +----+------+-----+--------+------+ | id | from | to | viewed | data | +----+------+-----+--------+------+ | 6 | 10 | 1 | true | .... | | 7 | 8 | 6 | true | .... | | 8 | 10 | 1 | true | .... | | 9 | 6 | 8 | true | .... | | 10 | 2 | 3 | true | .... | | 11 | 1 | 10 | true | .... | | 12 | 8 | 6 | true | .... | +----+------+-----+--------+------+ As you see from the ideal result set we have three groups. Therefore the desired query for the viewed results should show a maximum of 3 rows for each grouping it finds. In this case these groupings were 10 with 1 and 8 with 6, both which had three rows to be shown, while the other group 2 with 3 only had one row to be shown. Please note that where from = x and to = y, makes the same grouping as if it was from = y and to = x. Therefore considering the first grouping (10 with 1), from = 10 and to = 1 is the same group if it was from = 1 and to = 10. However there are plenty of groups in the whole table that I only wish the 3 most recent of each to be returned in the select statement, and thats my problem, I not sure how that can be accomplished in the most efficient way possible considering the table will have hundreds if not thousands of records at some point. Thanks for your help. Note: The columns id, from, to and viewed are indexed, that should help with performance. PS: I'm unsure on how to name this question exactly, if you have a better idea, be my guest and edit the title.

And also, what's important is the sql that's being generated: INSERT INTO concept_class (id, oid, description, label) VALUES (?, ?, ?, ?) bind = [LOINC_TEST, 2.16.212.31.231.54, This is a meta data file for LOINC_TEST, loinc_test] INSERT INTO concept (concept_key, description, label, code, concept_class_id) VALUES (?, ?, ?, ?, ?) bind = [27, description_1, label_1, code_1, Concept] The reason this is failing is obvious: It's inserting the word Concept for the concept_class_id. It should be inserting the word LOINC_TEST. I can't figure out why it's using this word. I've used the debugger to look at the Concept and the ConceptClass instance and neither of them contain this word. I'm using eclipselink. Does anyone know why this is happening?

  • How to get user input before saving a file in Sublime Text

    - by EddieJessup
    I'm making a plugin in Sublime Text that prompts the user for a password to encrypt a file before it's saved. There's a hook in the API that's executed before a save is executed, so my naïve implementation is: class TranscryptEventListener(sublime_plugin.EventListener): def on_pre_save(self, view): # If document is set to encode on save if view.settings().get('ON_SAVE'): self.view = view # Prompt user for password message = "Create a Password:" view.window().show_input_panel(message, "", self.on_done, None, None) def on_done(self, password): self.view.run_command("encode", {password": password}) The problem with this is, by the time the input panel appears for the user to enter their password, the document has already been saved (despite the trigger being 'on_pre_save'). Then once the user hits enter, the document is encrypted fine, but the situation is that there's a saved plaintext file, and a modified buffer filled with the encrypted text. So I need to make Sublime Text wait until the user's input the password before carrying out the save. Is there a way to do this? At the moment I'm just manually re-saving once the encryption has been done: def on_pre_save(self, view, encode=False): if view.settings().get('ON_SAVE') and not view.settings().get('ENCODED'): self.view = view message = "Create a Password:" view.window().show_input_panel(message, "", self.on_done, None, None) def on_done(self, password): self.view.run_command("encode", {password": password}) self.view.settings().set('ENCODED', True) self.view.run_command('save') self.view.settings().set('ENCODED', False) but this is messy and if the user cancels the encryption then the plaintext file gets saved, which isn't ideal. Any thoughts? Edit: I think I could do it cleanly by overriding the default save command. I hoped to do this by using the on_text_command or on_window_command triggers, but it seems that the save command doesn't trigger either of these (maybe it's an application command? But there's no on_application_command). Is there just no way to override the save function?

  • How do I pass session variables from one domain to another in PHP

    Hi everyone, I have encountered a situation where I need to pass $_SESSION variables from one domain to an iFrame page from another domain. I have spent the last 16 days trying various methods to no avail. I think that the only logical way would be to encode the variables in the url that calls the iFrame and decode them in th iFrame page. I am not sure how to go about this and I am looking for any samples, assistance etc that I can find. Thanks for any and all suggestions. Here is an example of what I am trying to do... Example: <!-- Note only using hidden as I didn't want to build the form at test phase--> <form name="test" method="post" action="iframe_test.php"> <input type="submit" name="Submit" /> <input type="hidden" name="fName" value="abc" /> <input type="hidden" name="lName" value="def" /> <input type="hidden" name="address1" value="ghi" /> <input type="hidden" name="address2" value="jkl" /> <input type="hidden" name="country" value="mno" /> <input type="hidden" name="postal_code" value="pqr" /> <input type="hidden" name="city" value="stu" /> <input type="hidden" name="retUrl" value="vwx"> <input type="hidden" name="decUrl" value="yz"> So from here I am hitting the iframe_test.php and doing the following: PHP Code: function StripSpecChar($val) { return (preg_replace('/[^a-zA-Z0-9" "-.@\:\/_]/','', $val)); } foreach ($_POST as $key => $val) { $_SESSION[$key] = StripSpecChar($val); } and I get a session array that looks like this: Code: Array ( [fName] => abc [lName] => def [address1] => ghi [address2] => jkl [country] => mno [postal_code] => pqr [city] => stu [retUrl] => vwx [decUrl] => yz ) Still all good so far....call the iFrame Code: <body> Some page stuff here <div align="center"><span class="style1"><strong>This is the iFrame Page</strong></span> </div> <div align="center"> <iframe src="https://www.other_domain.org/iframe/reserve.php" width="500" height="350" frameBorder="0"></iframe> </div> </body> So HOW do I take... $_SESSION['fName']['abc']; $_SESSION['lName']['def']; $_SESSION['address1']['ghi']; $_SESSION['address2']['jkl']; $_SESSION['country']['mno']; $_SESSION['postal_code']['pqr']; $_SESSION['city']['stu']; $_SESSION['retUrl']['vwx']; $_SESSION['decUrl']['yz']; and turn it into the encoded url that I am looking for? Further once that is done how to I get the session vars back as session vars on that new domain iFrame page...

  • using one data template in another data template in WPF

    - by Sowmya
    Hi, I have two data templates, one of which is the subset of another like below: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:igEditors="http://infragistics.com/Editors" xmlns:sys="clr-namespace:System;assembly=mscorlib" xmlns:controls="clr-namespace:Client.UI.WPF;assembly=Client.UI.WPF" xmlns:d="http://schemas.microsoft.com/expression/blend/2006" > <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="pack://application:,,,/Client.Resources.WPF.Styles;Component/Styles/CommonStyles.xaml"/> </ResourceDictionary.MergedDictionaries> <DataTemplate x:Key="XYZDataTemplate"> <Grid x:Name="_rootGrid" DataContext="{Binding DataContext}" HorizontalAlignment="Left" VerticalAlignment="Top"> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <controls:ValueDisplay Grid.Row="0" Grid.Column="0" LabelText="Build number" x:Name="buildNumber" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Margin="5,10,0,0"> <igEditors:XamTextEditor /> </controls:ValueDisplay> <controls:ValueDisplay Grid.Row="0" Grid.Column="1" LabelText="Tool version" x:Name="toolVersion" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Margin="20,10,0,0"> <igEditors:XamTextEditor IsReadOnly="True"/> </controls:ValueDisplay> </Grid> </DataTemplate> and the other is like below: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:igEditors="http://infragistics.com/Editors" xmlns:sys="clr-namespace:System;assembly=mscorlib" xmlns:controls="clr-namespace:BHI.ULSS.Client.UI.WPF;assembly=ULSS.Client.UI.WPF" xmlns:d="http://schemas.microsoft.com/expression/blend/2006" > <DataTemplate x:Key="ABCDataTemplate" > <Grid x:Name="_rootGrid" DataContext="{Binding DataContext}" HorizontalAlignment="Left" VerticalAlignment="Top"> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <controls:ValueDisplay Grid.Row="0" Grid.Column="0" LabelText="Build number" x:Name="buildNumber" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Margin="5,10,0,0"> <igEditors:XamTextEditor /> </controls:ValueDisplay> <controls:ValueDisplay Grid.Row="0" Grid.Column="1" LabelText="Tool version" x:Name="toolVersion" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Margin="20,10,0,0"> <igEditors:XamTextEditor IsReadOnly="True"/> </controls:ValueDisplay> <controls:ValueDisplay Grid.Row="0" Grid.Column="2" LabelText="Size" ShowUnit="True" x:Name="size" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Margin="20,10,0,0"> <igEditors:XamTextEditor/> </controls:ValueDisplay> </Grid> </DataTemplate> XYZDataTemplate is a subset of the ABCDataTemplate as the first two fields in both the data templates are common, so I was wondering if it is possible to replace the redundant code in the ABCDataTemplate with that of the XYZDataTemplate for code maintainability? Could anyone please suggest if would this be a right approach, if so how can I acheive that? Thanks in advance, Sowmya

  • Multiple data series in real time plot

    - by Gr3n
    Hi, I'm kind of new to Python and trying to create a plotting app for values read via RS232 from a sensor. I've managed (after some reading and copying examples online) to get a plot working that updates on a timer which is great. My only trouble is that I can't manage to get multiple data series into the same plot. Does anyone have a solution to this? This is the code that I've worked out this far: import os import pprint import random import sys import wx # The recommended way to use wx with mpl is with the WXAgg backend import matplotlib matplotlib.use('WXAgg') from matplotlib.figure import Figure from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigCanvas, NavigationToolbar2WxAgg as NavigationToolbar import numpy as np import pylab DATA_LENGTH = 100 REDRAW_TIMER_MS = 20 def getData(): return int(random.uniform(1000, 1020)) class GraphFrame(wx.Frame): # the main frame of the application def __init__(self): wx.Frame.__init__(self, None, -1, "Usart plotter", size=(800,600)) self.Centre() self.data = [] self.paused = False self.create_menu() self.create_status_bar() self.create_main_panel() self.redraw_timer = wx.Timer(self) self.Bind(wx.EVT_TIMER, self.on_redraw_timer, self.redraw_timer) self.redraw_timer.Start(REDRAW_TIMER_MS) def create_menu(self): self.menubar = wx.MenuBar() menu_file = wx.Menu() m_expt = menu_file.Append(-1, "&Save plot\tCtrl-S", "Save plot to file") self.Bind(wx.EVT_MENU, self.on_save_plot, m_expt) menu_file.AppendSeparator() m_exit = menu_file.Append(-1, "E&xit\tCtrl-X", "Exit") self.Bind(wx.EVT_MENU, self.on_exit, m_exit) self.menubar.Append(menu_file, "&File") self.SetMenuBar(self.menubar) def create_main_panel(self): self.panel = wx.Panel(self) self.init_plot() self.canvas = FigCanvas(self.panel, -1, self.fig) # pause button self.pause_button = wx.Button(self.panel, -1, "Pause") self.Bind(wx.EVT_BUTTON, self.on_pause_button, self.pause_button) self.Bind(wx.EVT_UPDATE_UI, self.on_update_pause_button, self.pause_button) self.hbox1 = wx.BoxSizer(wx.HORIZONTAL) self.hbox1.Add(self.pause_button, border=5, flag=wx.ALL | wx.ALIGN_CENTER_VERTICAL) self.vbox = wx.BoxSizer(wx.VERTICAL) self.vbox.Add(self.canvas, 1, flag=wx.LEFT | wx.TOP | wx.GROW) self.vbox.Add(self.hbox1, 0, flag=wx.ALIGN_LEFT | wx.TOP) self.panel.SetSizer(self.vbox) #self.vbox.Fit(self) def create_status_bar(self): self.statusbar = self.CreateStatusBar() def init_plot(self): self.dpi = 100 self.fig = Figure((3.0, 3.0), dpi=self.dpi) self.axes = self.fig.add_subplot(111) self.axes.set_axis_bgcolor('white') self.axes.set_title('Usart data', size=12) pylab.setp(self.axes.get_xticklabels(), fontsize=8) pylab.setp(self.axes.get_yticklabels(), fontsize=8) # plot the data as a line series, and save the reference # to the plotted line series # self.plot_data = self.axes.plot( self.data, linewidth=1, color="blue", )[0] def draw_plot(self): # redraws the plot xmax = len(self.data) if len(self.data) > DATA_LENGTH else DATA_LENGTH xmin = xmax - DATA_LENGTH ymin = 0 ymax = 4096 self.axes.set_xbound(lower=xmin, upper=xmax) self.axes.set_ybound(lower=ymin, upper=ymax) # enable grid #self.axes.grid(True, color='gray') # Using setp here is convenient, because get_xticklabels # returns a list over which one needs to explicitly # iterate, and setp already handles this. # pylab.setp(self.axes.get_xticklabels(), visible=True) self.plot_data.set_xdata(np.arange(len(self.data))) self.plot_data.set_ydata(np.array(self.data)) self.canvas.draw() def on_pause_button(self, event): self.paused = not self.paused def on_update_pause_button(self, event): label = "Resume" if self.paused else "Pause" self.pause_button.SetLabel(label) def on_save_plot(self, event): file_choices = "PNG (*.png)|*.png" dlg = wx.FileDialog( self, message="Save plot as...", defaultDir=os.getcwd(), defaultFile="plot.png", wildcard=file_choices, style=wx.SAVE) if dlg.ShowModal() == wx.ID_OK: path = dlg.GetPath() self.canvas.print_figure(path, dpi=self.dpi) self.flash_status_message("Saved to %s" % path) def on_redraw_timer(self, event): if not self.paused: newData = getData() self.data.append(newData) self.draw_plot() def on_exit(self, event): self.Destroy() def flash_status_message(self, msg, flash_len_ms=1500): self.statusbar.SetStatusText(msg) self.timeroff = wx.Timer(self) self.Bind( wx.EVT_TIMER, self.on_flash_status_off, self.timeroff) self.timeroff.Start(flash_len_ms, oneShot=True) def on_flash_status_off(self, event): self.statusbar.SetStatusText('') if __name__ == '__main__': app = wx.PySimpleApp() app.frame = GraphFrame() app.frame.Show() app.MainLoop()
